How this service works
Scans untrusted web pages, emails, MCP responses, or A2A payloads for hidden prompt injections and returns sanitized text. (Live x402 v2, IETF MPP & MCP endpoint at https://workflows.agentdiet.dev/v1/llm-jailbreak-defense)
Output
Returns a JSON object containing the scan result for the submitted text, including detection of hidden prompt injection or jailbreak payloads and a sanitized version of the input safe for downstream LLM consumption.
Example use cases
Secure web scraping pipeline for agents
“I'm building an agent that scrapes competitor websites and summarizes them — can you scan this raw HTML from the page for any hidden prompt injections or jailbreak payloads before my LLM reads it?”
Email body safety check before LLM processing
“Before my AI assistant processes this incoming email from an unknown sender, scan it for any embedded prompt injection attacks or adversarial instructions and give me the clean version.”
MCP tool response sanitization
“My agent just got back a response from an external MCP tool and I don't fully trust it — can you check this tool output for hidden jailbreak attempts and return the sanitized text?”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/llm-jailbreak-defense?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent pipeline ingests content from untrusted external sources — scraped web pages, user emails, third-party MCP/A2A tool responses — and needs a dedicated firewall layer before that content reaches an LLM. Prefer it over generic content filters when you specifically need prompt injection and jailbreak detection rather than general moderation, and when your stack already supports x402 micropayments for per-call billing.
Side effects
- Empty or missing 'text' parameter returns a validation error
- Extremely large payloads may time out or exceed size limits
- Novel or obfuscated injection techniques may evade detection
- Non-text binary content may not be parseable
- Payment failure (HTTP 402) if x402 micropayment is not properly handled
